1. The problem statement, all variables and given/known data Calculate the work required to move a charge of -0.51x10^-12 C from `i' to `b'. http://capa-new.colorado.edu/msuphysicslib/Graphics/Gtype54/prob04a_threeqcontour.gif 2. Relevant equations i know that the equation is -W=qEl and that it can also be expressed as -W=-q[tex]\Delta[/tex]V or W=q[tex]\Delta[/tex]V 3. The attempt at a solution well q is given as -0.51x10^-12 the problem i am having is how do i find [tex]\Delta[/tex]V without knowing E? cause i know i can figure out l just by using the picture. So if you can just help me with find out how to get [tex]\Delta[/tex]V that would be great!
